Hi- the A620 was (and still is..!) a great little camera and I had the pleasure of owning one some time ago. I "upgraded" with the A710is- still at 7mp but with a 6x zoom and image stabiliser. Alas,these have long gone too,though I'm still hunting for a clean second hand one on ebay..lol..!!
If your looking at a new Canon "point and shoot", the A3200is isn't a bad place to start and is fairly inexpensive too. With an image stabilised 5x zoom(28-140mm) and 14mp....
